when an electron is added to a neutral atom, energy is...? Answers Below!?

Question

A. always absorbed
B. always released
C. eiher absorbed
D. burned away

Answer 1

I believe there is a mistake in the choices of answers you listed. Option C is supposed to be "either absorbed or released right?

Then, C is the correct answer. Some neutral atoms (non-metals that from anions) become more stable as the gain an electron, thus releasing energy. I put a link of electron affinity chart for your review. As you can see, the kJ are represented in negative value as expected.

Some neutral atoms (metals that from cations), need much energy inputted to gain an electron, thus absorbing energy to become very unstable.

Answer 2

while an atom's valence bands are partly crammed, then the potential required for taking photos or sharing one greater electron is decrease than if each and all of the bands have been already crammed. this is by technique of the fact while each and all of the bands interior of an potential point s, p, d, f are crammed, the subsequent available empty spot for an electron to occupy would be at a extremely lots larger potential point than it may if it grew to become into interior the present potential band. considering the fact that bonds are made while atoms seize electrons, then aspects with partly-crammed valence bands would be greater reactive than aspects with complete valence bands with the aid of fact it somewhat is going to take much less potential to reason a bond.

Answer 3

i believe a, because electrons are what contain the energy in the atom
